PERAlVlBULTlNG CHAIR.

SPECIFICATION forming part of Letters Patent No. 547,419, dated October8, 18945. Application filed January 2, 1895i. Serial No. 5331507- (NOmodel-l To all whom it may concern:

Be it known that I, LEMUEL ANDRUs CHI` CHESTER, a citizen of the UnitedStates, and a resident of Chichester, county of Ulster, and State of NewYork, have invented certain new and useful Improvements in Perambulatingand other Chairs, of which the following is a specication, referencebeing had to the accompanying drawings, forming a part thereof, in whichsimilar letters of reference indicate corresponding parts in bothfigures.

This invention relates to perambulating chairs, and has) for its objectto provide a simple, cheap, readily constructed, durable, andperfectly-operating device of this character in which thesupporting-beam of the wheels and the sides of the chair-seat will beconstructed in one piece to form springs to cushion the chair and inwhich an improved foot-rest is provided.

The invention consists in the novel construction and arrangement ofparts hereinafter fully described.

In the accompanying drawings, Figure l is a side elevation of a chairembodying my invention. Fig, 2 is a front elevation of the same.

In the practice of my invention I construct two side beams A, havingdownwardly-projecting rear ends A and upwardly curved at the front toform semicircular or segmental portions A2, from which projectrearwardly, parallel to the said side beams, extensions B. The said sidebeams A, the ends A', the forward portions A2, and the extensions B ofeach side are all formed in one piece of semielastic or spring materialcapable of supporting the whole weight of the chair and the occupantthereof and preferably of wood, which in practice is the only materialwhich I have found suitable and operative.

The beams A are connected at the front and rear by means of the axles aa', on which are mounted upon the outer ends thereof the front and rearwheels C C', and the extensions B are connected by the chair-seat D,which extends transversely between the same.

The extensions B are downwardly turned at the rear to form curved armsB', which are secured by means of pins b to the lower ends of the sidebars E, which form the main part of the chair-back and projectappreciably below the chair-seat D, where they are provided with rubbercushioning blocks or balls E. The side bars are secured to each side ofsaid chair-seat, and are rearwardly curved at the top, where they areconnected by means of a cross-bar c. Beneath the cross-bar c, I secure,between the arms E, fiat cross-bars d toward the top and near the bottomthereof, between which are inserted vertical rods or bars e.

The arms F ot' the chair are suitably curved, as shown in Fig. l, toform flanges F upon the ends thereof, which are secured to theextensions B and the side bars E of the chairback by means of pins b.Said arms F are also connected to the extensions B by means of verticalbars or rods f.

At the forward end of the device the extensions B have pivoted therein,in front of the chair-seat D, bars G, which are supported at anobliquely-outward angle by resting upon the forward axle a, and areprovided with integral flanges or extensions G', ranging at right anglestherewith and having secured between the same a foot-rest g.

The operation of the device will be readily understood from theforegoing description,

taken in connection with the accompanying drawings. When the occupant ofthe chair seats himself thereon, the burden of the Weight is taken bythe extensions B of the beams A, which yield beneath said weight andserve, by reason of their elasticity, as springs for said chair, wherebythe rear portion thereof is downwardly yielding, and too greatdepression of the seat is prevented and contact between the lower endsof the side barsE and the ends A of the beams cushioned by means of therubber blocks or balls E. The foot-rest g is adjustable to the angle orposition of the limbs by reason of the pivoting of the bars G thereof inthe extensions B.

The advantages resultant from the use of the invention will be manifestto all who are conversant with the general class of devices to which thesame appertains. l

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. A perambulating chair comprising side beams having downwardly turnedrear ends, integral semi-circular arms at the front there- IOO ofprovided with extensions ranging rearwardly therefrom parallel with thebeams and downwardly turned at the rear, said beams and extensions beingformed of spring Wood, axles connecting the beams together, havingwheels thereon, a chair seat secured to said extensions, a chair backhaving side bars which project downwardly below said seat and aresecured at their lower ends to said extensions, elastic blocks upon saidlower ends adapted to engage the ends of the beams and cushion thecontact of said side bars therewith, and arms secured to the bars ofsaid chair back and to the extensions, substantially as shown anddescribed.

2. A perambulating chair comprising side beams having downwardly turnedrear ends, integral semi-circular arms at the front therel of providedwith extensions ranging rearwardly therefrom parallel with the beams,said beams and extensions being formed ot' spring wood, axles connectingthe beams together at front and rear, having wheels mounted thereon,arms projecting downwardly from the rear ends of the extensions, a chairseat secured to the same, vertical and upwardly curved side bars securedto said seat projecting below the same, and secured to the arms of theextensions, rubber blocks upon the lower ends of said bars to cushionthe contact thereof with the beams, cross-bars connecting the saidvertical side bars together, and rods or bars between the same to form achair back, arms secured to said vertical bars and to the extensions,and a foot rest pivoted in said ex tensions and resting upon the forwardaxle of the chair, substantially as shown and described.

In testimony that I claim the foregoing as myinvention I have signed myname,in presence of two witnesses, this lst dayY of Decem ber, 1894.
